DESCRIPTION OF THE PREFERRED EMBODIMENTS

Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a block diagram showing an arrangement of a local radio base station apparatus according to an embodiment of the invention. FIG. 2 is an explanatory view showing a registered content of a memory included in the local radio base station according to the embodiment of the invention.

In FIG. 1, a numeral 10 denotes a local radio base station for local use. A numeral 11 denotes a public representative radio mobile station the location of which is registered under the control of the local radio base station 10. A numeral 12 denotes a plurality of personally owned public radio mobile stations. The public radio mobile station 12 is enabled to give a call or accept a call through the public representative radio mobile station 11. The local radio base station 10 includes a communication path switch 13, a central control unit 20 for controlling the whole of the local radio base station, a memory 60, and a voice processor 50, the latter two of which are connected to the central control unit 20.

The communication path switch 13 serves to form a communication path between a network side belonging to a public line and the public representative radio mobile station 11 and the public radio mobile station 12 both of which belong to a local line. The central control unit 20 includes a call accepting unit 21, a calling unit 22, an additional number analyzing unit 23, and a voice processor control unit 24. The memory 50 includes a table 51 for registering a phone number of the public representative radio mobile station, a local number table 52 for registering a local number, an additional number storing unit 53, and a storing unit 54 for storing a phone number of the public radio mobile station for giving a calling request.

In FIG. 2, the table 51 for registering the phone number of the public representative radio mobile station included in the memory 50 contains representative public numbers D11 to D1n of the public representative radio mobile station to be representatively called. The local number table 52 contains the phone numbers (public numbers) D12 to D1m of the public radio mobile station and the allocated local numbers F1 to Fm enabled under the control of the local radio base station 10. When called from the public line by the phone number of the public representative radio mobile station 11 plus the additional number, the additional number storing unit 53 operates to temporarily store the called number (representative public number) D11 to D1n and the corresponding additional numbers F1 to Fm. The storing unit 54 for storing the phone number of the public radio mobile station 12 for issuing a calling request operates to temporarily store the caller numbers (public number) D12 . . . of the public radio mobile station for issuing a call to the public line and the used representative numbers D11 . . . of the used public representative radio mobile station.

Now, the description will be oriented to the operation of the local radio base station apparatus according to an embodiment of the invention.

First, when called from the public line by the phone number of the public representative radio mobile station plus the additional number, the central control unit 20 operates to match the called number to the numbers registered in the table 51 and determine whether it is matched to any one of the numbers. When matched, the accompanied additional number F1 is temporarily stored in the additional number storing unit 53. Then, the call accepting unit 21 performs an operation of linking a call with the public representative radio mobile station 11. After the matching identification is terminated, the additional number analyzing unit 23 operates to determine whether the additional numbers F1 stored in the additional number storing unit 53 are matched to the local numbers registered in the local number table 52. Only when one match takes place, the corresponding public radio mobile station 12 is locally called by the public number D12. After the station 12 responds to the call, the communication path switch 13 operates to switch the call link from the public representative radio mobile station 11 to the public radio mobile station 12. The radio link of the public representative radio mobile station 11 is made open when the foregoing identification is terminated. However, the called state in the local radio base station 10 is held until the call link of the public radio mobile station 12 is cut off.

The foregoing operation makes it possible for the personally owned public radio mobile station 12 to be used for local business without making the phone number of the mobile station 12 open to the calling person.

On the other hand, when the public radio mobile station 12 operates to issue a calling request for the public line, first, the public representative radio mobile station 11 is locally called by the requesting mobile station 12. At this time, the storing unit 54 for storing the phone number of the public radio mobile station 12 for requesting a call operates to store the phone number D12 of the public radio station 12 having requested a call to the public line and the phone number D11 of the public representative radio mobile station 11 having being locally called. After establishing the radio link of the public representative radio mobile station 11 with the public line, the local radio base station 10 enables the calling unit 22 to give a call to the destination phone number requested to be called by the public radio mobile station 12. After the identification is terminated, the public radio mobile station 12 operates to retrieve the public radio mobile station number D11 of the mobile station having requested the call, stored in the storing unit 54 and enables the communication path switch 13 to switch the call link from the public representative radio mobile station 11 to the public radio mobile station 12.

The radio link of the public representative mobile station 11 is made open at a time when the foregoing identification is identified. However, the called state in the local radio base station 10 is held until the call link of the public radio mobile station 12 is cut off.

The above series of operations make it possible for the personally owned public radio mobile station 12 to be used for local business without being charged with it.

In the foregoing case that there is a call from the public line by the phone number of the public representative mobile station plus the additional number, when the public number registered in the local number table 52, which corresponds to the local number matched to the additional number F1, is a voice processor number, a voice communication path is connected with the voice processor through the effect of the voice processor control unit 24.

This function provides a mail recording service in a specific local area where the public radio mobile station is in use.

As set forth above, the local radio base station apparatus according to the present invention provides the public representative radio mobile station in the local radio base station so that the calling from the personally owned public radio mobile station or the called thereby is realized through the public representative radio mobile station. At the same time, the phone number of the personally owned public radio mobile station is not made open to the calling party when the mobile station may accept the call from the public line and further may be oriented to commercial use inside of the local area.

Moreover, the local radio base station apparatus according to the present invention prevents the personally owned public radio mobile station from being charged when the mobile station gives a call from the local area to the public line.

The local radio base station apparatus according to the present invention also provides a mail recording service inside of a specific local area where the public radio mobile station is in use by connecting the local radio base station to the voice processor.
